Uddhava then stated that renouncing material things in a spirit of detachment is the source of the highest auspiciousness, but such renunciation is certainly extremely difficult to accomplish for living entities other than the devotees of the Supreme Lord, because they are very attached to sense gratification. Uddhava expressed the need for some instruction by which foolish persons who misidentify the body as the self can be convinced to carry out their duties in accordance with the order of the Supreme Lord. Even great demigods like Brahmā are not completely surrendered to the Lord, but Uddhava declared that he himself had taken shelter of the only true instructor of the Absolute Truth — Lord Nārāyaṇa, the all-perfect, all-knowing master of Vaikuṇṭha and the only real friend of all living entities. Hearing this, the Supreme Lord replied that actually the jīva soul is his own guru. Within this human body, the living beings can search out the Supreme Lord by positive and negative means and ultimately achieve Him. For this reason the human form of life is most dear to the Supreme Personality of Godhead. In this regard, Lord Kṛṣṇa began to describe an ancient conversation between a brāhmaṇa avadhūta and the great king Yadu.
